ALFRED GREENAWAY, OF LOUISVILLE, KENTUCKY.

FRANKLlN STOVE AND FlR E-GRATE.

SPECIFICATION forming part of Letters Patent No. 258,575, dated May 30,1882. Application filed January 29, 71881. (No model.)

To all whom it may concern: Be it known that I, ALFRED GREENAWAY, of thecity of Louisville, in the county of J efferson and State of Kentucky,have invented a certain new and useful Improvement in Franklin Stovesand Fire-Grates and I do hereby declare that the following is a full,clear, and exact description of the construction and operation of thesame, reference being bad to the accompanying drawings, forming part ofthis specification.

This invention is in the nature of improve ments in fire-places andequivalent or similar heating apparatus; and the invention has for faceof the stove or grate, the smoke-hood be-- its object the increment ofthe heat-evolving surface of such grates, and at the same time providingagainst the escape of noxious products of combustion and insuringperfect draft.

To these ends the invention consists in the combinations andarrangements of parts hereinafter more particularly specified andclaimed.

In the accompanying drawings,illustrating my invention, in the severalfigures of which like parts are similarly designated, Figure 1 is aperspective view, looking squarely in the ing in place. Fig. 2 is asimilar View with the hood removed. Fig. 3 is a perspective View,looking at the roar. Fig. 4 is a central vertical cross-section. Fig. 5is a perspective view of a fire-place grate, looking squarely in theface thereof. Fig. 6 is a plan View of a mica blower, and Fig. 7 is alongitudinal horizontal section of the back of the basket.

In order to obtain a greater extent of heatexit than has heretofore beenhad in grates, I make the grate-opening in the frame Q about one-thirdhigher than is ordinarily done, and in order to remedy any defectivedraft or the out-throw of smoke-incident to such increased opening, Iprovide a fixed or movable hood, 0, which I arrange at the top of theopening. This hood I prefer to make of a metallic frame, light andornate, and provided With mica sheets secured therein, the said hoodprojecting somewhat below the edge of the opening, as shown in Fig. 4.This hood will, if the stove or grate draw badly or smoke, insureperfect draft and obviate smoking, and will not interfere with or reducethe increased heat-outlet. Ordinarily a basket eighteen inches long hasa frameopenin g fourteen inches high between it and the unof the bars.

der side of the frontarch butin my construction I increase this openingone-third, thus making the proportion twenty-one of opening to eighteenof basket, and I observe these proportions asnearly as possible in allsizes.

The grate E, I prefer to set a little higher than usual, and its back'F,I prefer to arrange at an angle of about forty-five degrees to thehorizontal. The back F is secured detachably to the front E by means ofa lug, a, entering between the grate-bars in front, and two lugs, b,resting against the rear edge of the frame This back is slittedtransversely and obliquely to form draft-openings c, and its ends turnedback to form wings or deflectors, which are perforated at d. Thisslitting and perforating of this fire-back insures the combustion of thefuel and gases at the back of the grate, thereby increasing the heat andinsuring the perfect and complete consumption of the fuel.

G is an air-chamber, preferably formed of sheet metal and arranged inthe rear of the fire-chamber.

His an air-conduit leading from the front of the grate on the hearth Sbeneath thegrate into the chamber G. The air heated in this chamber isconducted through lateral pipes or flues I to the hot-air chamber P, orto registers V, as may be desired, for distribution into the apartmentsto be heated.

K is a transverse metal bar, upon which the tile L is supported. Thistile is somewhat larger than usual, and completely fills in the back ofthe stove or grate. It is cemented in place to make a tight joint, andits wide and enlarged top, combined with the cap or arch N, forms thesmoke-flue 0. Above the fluecap is a chamber, P, which in Franklinstoves may have a perforated top, J, and receive the hot air from thepipes I for distribution into the apartment. The cap N is cemented inplace to make a close and smoke-tight joint beneath the chamber P. It isthe ordinary fender.

In Fig. 6, I have shown a blower for use in connection with the grate.This blower is formed as a skeleton frame filled in with mica.

In Fig. 5, I have shown a fire-place grate arranged in accordance withmy invention, A being the mantel; B, a cross-piece over the extendedopening, 0 being the hood in said extended opening; D, the blower, whichmay be hinged to the grate-framing. Otherwise the construction issubstantially the same as heretofore described.

By my invention 1 am enabled to secure a greater quantity of heat thanhas been possible with constructions heretofore in use.

'What I claim is 1. A basket, E, and the surrounding frame Q, having itsopening extended about the basket, as shown and described, to secure alarge heat-outlet, combined with the tile L, the cap N, and thesmoke-flue between the two, and the mica-filled hood 0, placed about theopening of said frame to insure a perfect draft and prevent smoking, allconstructed and arranged to operate substantially as set forth.

2. The tile L, as shown and described, cemented in place, combined withthe grate, the grate-frame Q, with its enlarged opening and hood, andthe cap N, substantially as shown and described, whereby an enlargedheat-opening is obtained and a perfect draft insured.

3. In agrate, the frontportion, E, made with grate-bars, combined withthe back F, having project-ions a I) to interlock with the frontportion, E, to hold said back at or about at an angle of forty-fivedegrees to the horizontal, substantially as described.

4. The air-conduit H, the air-chamber G, the grate E, its back F, thefines I, the tile L, and the chamber P, combined and arranged as shownand described, and for the purpose specified.

ALFRED GREEN AWAY.
